This blade is made from High Carbon Steel (HCS). It is a material that can withstand bending and therefore is best suited for cutting softer materials such as softwood, soft plastics and wood fibreboards. he blade attachment is a bayonet or T-shank and has been designed for quick and easy blade changes. The shank shape ensures a secure fit, reducing the risk of slipping or coming loose during operation. The ground teeth have sharper edges which leave a smooth & accurate cutline.
